DEVICE FOR CONVERTING RECIPROCATINQ INTO ROTARY MOTION.

SPECIFICATION forming part of Letters Patent No. 255,735, dated March28, 1882. Application filed September 23, 1880. Renewed Septcmberlfi,1881. (X model.)

To all whom at may concern:

Be it known that I, WILLIAM H. RY'lI-IER, of Somonauk, in the county ofDe Kalb and State of Illinois, have invented a new and useful Device forConverting Iteciprocations into Rotary Motion, applicable to thepropulsion of rotary machines by power derived from the pitman ot'a.wind-wheel, 85c; and I do hereby declare that the following is a fulland exact description of the same.

The principal points of advantage of my machine may be stated asfollows: First, acontinuous uniform rotary motion is obtained from areciprocatory motion which may be I5 fluctuating in speed; second, whenfrom any cause the wind-v heel or the rotary converter ceases tooperate, the pitman and the rotary converter become automaticallydetached from each other; third, the rotary motion obtained is moreuniform than the reciprocation of the driving-pitman; fourth, the rotarymotion is continuous without adding any device whereby the governing oi"the wheel may possibly be prevented; fifth, the power to propel themachinery resides in two or more weights or springs which are flexed bythe rotation of the driving-shaft operated by the wind-wheel, so thatthe propelling-power for the machinery is constant, notwithstanding themotion of the 0 wind-wheel may be iuconstant.

My invention consists, first, in the peculiar devices whereby thereciprocating part may be automatically detachedfrom the rotary partupon the arrest of either; second, in the 5 method whereby thereciprocating pitman acts only upon the rotary to wind up or flex theimpellin g-sprin gs without acting directly upon the mechanism whichimpels the driven machines; third, in the device by which the dogs orclutches attach and detach themselves to or from the pitman fourth, thepeculiar construction of the ratchet-plates and chain or band wheels,whereby the same is adapted to any size of wheel and any length ofcrankshaft stroke; filth, the clutch-shaft with devices which causeone-or bot-h to go out of action when not required.

That others may fully understand my invention, I will particularlydescribe it, having reference to the accompanying drawings,

wherein- Figure 1 is a perspective view of my device in operativeposition. Fig, 2is a central transverse sectional elcvation ot the sameon line 2 2. Fig. 3 isa longitudinal sectional eleva- 5 tion on line 33, Fig. 4 is a transverse sectional elevation on line 4 4.

The wind-wheel, which may be of any proper construction, is supportedupon aframe-work as usual.

O is the pitman of said wind-wheel, drlven by the crank-shaft ot' thewheel and communicating a reciprocating motion to the mechanism below.The lower end of the pitman 0, moves in guides a a, and is provided oneach side with clips or notches b b, to engage with hooking-pawls D D,which are hung in the reciprocating bars E E, which also move in theguides at a, parallel with the pitman O.

A transverse shaft, F, is mounted in the frame Gr below the pitman O,and said shaft is provided with two drums, H, upon which are woundchains or cords d, the outer ends whereof are attached to the lower endsof the bar E, so that when-said barsare drawn npsaid drums 7 will becaused to rotate upon said shaft. Each drum H is provided at oneend withagrooved flange or pulley, it, upon which is wound a cord or chain, theouter end of which is connected to the propelling-spring I. Outside ofeach pulley it there is a flanged collar, J, the edge of which is formedwith ratchet-teeth, and a pawl, e, is placed upon the pulley h, toengage with said teeth. The elfect of this arrangement is to permit thedrum H to revolve backward freely when the bar E is drawn up, but tocause the shaft F to revolve with itwhen the spring I retracts andcauses said drum to revolve forward again. In that way the spring I isalternately flexed and released, and as 0 there are two or more of saidsprings, they may be brought alternately into action, and thus maintaina constant pressure to revolve the shaft F.

By means of a train, K, L, M, &c., the mo- 5 tion of the shaft F may bespeeded up or down,

out ofrngagemen't with the clips I) b as soon as they are liberated, andremain out of engagement until by the descent of the bar E they areagain thrown forward by some positive means. This may be by acam-surface attached to the side of the frame or by a spring, 9. Aswinging gate, P, may be hung between the cletts b, to be alternatelypushed aside by the pawls D as they enter and engage said cleft, andthereby to prevent the engagement of more than one pawl'at the sametime. The springst' 1' support the bars E E and keep the cords or chains(1 d always taut, and therefore keep the dogs 1) out of engagement untilthe power of the spring I is nearly exhausted. If, therefore, themachinery is slow running, the pitman, after having lifted both bars E,may make several rceiprocations without effecting any work; but usuallyone of said rods will be lifted at each reciprocation.

The mechanism as above described is supported to stand directly beneaththe windwheel butthis location may not always be convenient. Thedirection of the pitman C may be changed'from vertical to horizontal, asdesired, by means of a bell-crank, and the position of the rotarymechanism will then be correspondingly changed.

Having described my invention, what I claim as new isv l. Thereciprocating bar 0, provided with the clips I) b, combined with thebars E E, each provided with the dogs D D, springs gand t, chain orcords d, and chums H, as set forth.

2. The reciprocating bar 0, provided with clips b b, ombined with thereciprocating bars E E, provided with dogs D D, weighted at the back, soas to fall out of engagement, and spring 9, near the bottom of thereciprocation, to push said (logs into position for engagement, as setforth.

3. A device for converting motion, to be placed intermediately betweenthe prime mover and the machine to be driven, provided with springs orweights whereby the machinery may be driven, and winding-drum actuatedby the reciprocation of the prime mover, whereby the motion imparted tothe driver-machine is not made irregular by fluctuations of speed of theprime mover.

4. A motor actuated by springs or weights combined with mechanism drivenby a reciprocating pitman, whereby duringthe operation of said motorsaid springs or weights are being constantly wound up and their tensionrenewed.

5. The reciprocating bars E E and the dogs D D, combined with thereciprocating bar 0, provided with clips I) b, and the intermediateswinging gate, P, for the purpose set forth.

6. A reciprocating bar or pitman, 0,0011]- bined with two parallelalternately-reciprocat ing bars, E E,provided with mechanism wherebysaid bars will be alternately engaged with said pitman to be actuatedthereby, and connected with said bar E rotary reciprocating drumsmounted upon a revolving shaft, with automatic clutches and retractingsprings or weights, whereby the alternating reciprocation of said bars EE and their connected drums is converted into a continuous rotation ofsaid shaft, as set forth.

7. The reciproeatingbar 0, provided with the clips I) b, combined withthe bars E E, each provided with the dogs D D, springs g g and M, chainsor cords d d, and drums H H, as and for the purpose set forth.
